This multi-cavity injection molding service is dedicated to medical device housings, from diagnostic instrument shells to patient monitor enclosures and portable analyzer cases. Tooling is machined from S136 ESR stainless steel, hardened and polished to SPI A1, ensuring corrosion resistance, easy cleaning and mirror-smooth surfaces that meet the visual and hygienic expectations of medical equipment.
With 2 to 8 cavity configurations and hot runner systems, we balance throughput and tooling cost for medical OEMs who need dependable volume without compromising dimensional accuracy.

Medical housings produced with this service equip diagnostic analyzers, infusion pumps, patient monitors, dental equipment, surgical instrument handles and home healthcare devices. The combination of precise snap-fit geometry, chemical-resistant materials and clean molding makes these parts suitable for devices that require repeated disinfection with alcohol or mild bleach solutions.
Company StrengthSince 2007, Xiamen KDT Technology Co., Ltd. has grown into a full-service injection molding manufacturer with an integrated tooling room, CNC and EDM departments and injection machines ranging from 90 to 650 tons. Our 40 to 50 person team manages medical and industrial programs for clients in Germany, the United States, Japan and Southeast Asia, exporting 80% to 90% of production volume.
Product SolutionsOur medical program workflow begins with DFM analysis that checks draft angles, rib geometry and gate placement against cleanability requirements. We then simulate filling and cooling with mold flow software, manufacture the tool with documented steel certification, and validate trial shots through OTS and golden sample procedures. For serial production we provide lot traceability, material certificates and process parameter records for every batch.

A Japanese diagnostic device maker relocated a 6-cavity analyzer housing program to our factory. We delivered S136 ESR tooling with hot runner control, achieved a 42-second cycle and shipped 300,000 housings per year with zero field complaints over two years. A European home healthcare brand also uses our 4-cavity tool for a wearable monitor shell, cutting their landed cost by 22%.
Frequently Asked Questions| Question | Answer |
|---|---|
| Do you supply material biocompatibility documentation? | Yes, we provide ISO 10993 or USP Class VI test reports from our certified material suppliers. |
| Can you handle cleanroom molding? | We operate a dust-controlled workshop; for ISO Class 7 or higher we partner with certified cleanroom facilities. |
| What is the typical mold life for S136 tools? | With scheduled maintenance, S136 ESR molds exceed 500,000 shots for unfilled medical grades. |
| Do you support design changes after DFM? | Yes, we freeze the design only after your written approval of the DFM and mold flow reports. |
| Can you mold transparent medical parts? | Yes, with PC or PMMA using mirror-polished cavities and optimized gating to avoid flow marks. |
| How are medical parts packaged? | Double PE bagging with desiccant in medical-grade cartons, with lot numbers printed on every box. |
Medical housings are packed under controlled conditions using anti-static bags, desiccant and clean cartons with lot traceability labels. Each batch is verified against the approved golden sample, and final inspection follows AQL 2.5 with dimensional and cosmetic records archived for your quality team.
